Abstract: Data security is the bottom line of network security and the top priority of the development of information technology innovation industry. At present, the construction of information technology innovation field is mainly based on infrastructure and business applications, and there is still a need for continuous improvement in data protection. Through the introduction of innovative research on trusted computing technology, continuous protection of big data, emergency takeover of business system, early warning and defense and other technologies. This paper explains that the data backup and recovery system of information innovation platform guarantees that the data is not lost from the datalevel security technology, ensures that the business does not stop from the applicationlevel security technology, and realizes the multidimensional unified disaster recovery management of different branches and different users from the platform level, so as to provide safe, reliable, efficient, comprehensive and sustainable information security protection for domestic information systems.

Key words: credible, continuous protection, emergency takeover, disaster management, efficient redeletion
